Description
Body short, 39 segments, 16 pairs of
elytra. Anterior margin of
prostomium with a pair of acute anterior peaks. Lateral antennae inserted ventrally (beneath prostomium and median antenna). Palps, antennae, dorsal and ventral cirri with papillae. Notochaetae about as thick as neurochaetae. Unidentate and bidentate neurochaetae present.
''Eucranta'' are short-bodied scale worms with 36 to 40 segments and 15 pairs of
elytra. The
prostomium is bilobed anteriorly and a pair of cephalic peaks is present. The lateral antennae are located ventrally, directly beneath the median antenna ceratophore. The
neuropodial lobes are elongate.
The
notochaetae are distinctly thicker than the
neurochaetae; both are ornamented with transverse rows of small spines. The neurochaetae may be unidentate or bidentate and distinctive furcate neurochae are present.
